What is the class width? 

The class width is _______ .(Simplify your answer.)

Answer 1

Lower class limit of first class = 100 and Upper class limit of the first class = 120

Class Width: The difference between the upper and lower boundaries of any class. The class width is also the difference between the lower limits of two consecutive classes or the upper limits of two consecutive classes. It is not the difference between the upper and lower limits of the same class.

Class width is = (120-100)= 20
